Ninja Gaiden Sigma offers realistic battles and acrobatic ninja moves in your hands. As Ryu Hayabusa, you seek revenge after the slaughter of your clan by the Vigor Empire. All you have is your intelligence, sword, and abilities. Your weapons and skills in battle are exceptional, but only time will tell if they are enough to defeat the Holy Emperor and reclaim the magical sword known as "Ryuken." Upload your scores to Karma on the Playstation network and compare them to the leaderboards
